For decades the US military has used 30-75 MHz as its ground operations bands. This is the main band used by military ground forces. They do stay away from most of other service uses, but when needed they use whatever they want in this spectrum. It is 25 kHz dev FM.
The military is moving more to sat comm due to its security of a small dish on the ground pointed up and hard to intercept and they can link up to about any where in the world. Washington can give direct support to a mission 10,000 miles away. 73, ron, n9ee/r >From: ensemble953039 <[EMAIL PROTECTED]> >Date: 2007/07/29 Sun PM 03:53:55 CDT >To: Repeater-Builder@yahoogroups.com >Subject: [Repeater-Builder] Re: 4 meters > >Hi, > the "green hats" are the military and although we here in the U.K. >do have the 4m band it is at the top end of the "Tac" military band. > We don't seem to be bothered by them or them by us as we also >share that part of the spectrum with commercial interests,so with >all interests interwoven we all seem to get along. > >Adam g8umx > >--- In Repeater-Builder@yahoogroups.com, "JOHN MACKEY" <[EMAIL PROTECTED]> >wrote: >> >> What are "green hats"? >> >> ------ Original Message ------ >> Received: Sun, 29 Jul 2007 08:40:17 AM CDT >> From: Geert Jan de Groot <[EMAIL PROTECTED]> >> To: [EMAIL PROTECTED]: [EMAIL PROTECTED] >> Subject: Re: [Repeater-Builder] 4 meters >> >> > On 29 Jul 2007 10:39:32 -0000 Repeater-Builder@yahoogroups.com >wrote: >> > > I was just wondering if anyone had heard any actions to get >amateurs >> > > access to 4 meters (like European hams) once analog television >goes dark? >> > >> > There's only a limited set of European hams who have access to 4 >meters. >> > Analogue television went dark here (the Netherlands) 7 months >ago, >> > and the request was made, but the regulator turned it down: >> > the frequency was shared with green hats, and the're not letting >go. >> > >> > Would be nice, though. >> > >> > 73, >> > >> > Geert Jan PE1HZG >> > >> > > Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
